ments in the method of nia'miim-turing sauitary drinking eups. and its ohjeet is to produee a (-up from thin paratiin or like. paper resistant to the aetion of water and other liquids without the aid of pastes or adhe sires oi any kind. and requirin; hut a minimum quantity of material. and \\'lii('ll may also he so elieaply produeed as to warrant disearding the eup after the use for which it is produeed.

, In aeeordanee with the present invention a large number of eups may he produeed sueeessirely from a lone web of paratiin paper. simple elongated rertangular hlankshe in; eut sueeessively from the web. and earh hlank is folded upon itself-internnaliatelv of its length and then the side edges where meeting are pressed together and erimped to eanse eohesion of such edges. after whirh the joined edges are folded toward the eenter line of the hlank and pressed together and again erimped. and finally these i'olded edges are again folded over toward the renter line of the blank and pressed together and rriinped so that atthe edges of the hlank the paper is folded a plurality ottimes upon itself under pressure. and. with erimping or like indenting.aetion eansin e a strong uniting of the surtaees. it is rendered liquidproof by theparatlin present in the parallin paper. the said paratlin hein; sullieiently stron; to hold the parts in plaee. To use the rap it is compressed toward the renter line to eause that end of the enp remote from the intermediate told of the hlank to spread open for the reeeption of liquid. the foldedorer side edges or margins prerentin; separation of the sides of the enp at sin-h points. wherefore the enp may he used to rereive liquid for immediate use or t'or transportation for considerable distanees. and. moreover. the (nip may he filled several times witlioutiiability oi any water or other liquid leaking therefrom.

The cup. eornprises'hut two thicknesses of.

paraiiin paper. while the margins where the sides are folded over upon eaeh other do not exeeed five layers oi paper in thirkness. sueh thiekness heing to a great extent unnotieeahle. although sewing materiallr in stiffening the eup lengthwise. I

The improved eup is readily a'daptahle to manut'm-ture by very simple apparatu so that it is readily produeihle in a vending machine of small size. and small eost. whieh may he loeated in puhlie or semi-puhlie plaees. or wherever persons are ikely to de sire a eup for temporary use. and where it is eonnnon to provide a glass or enp l'or sneh use. \\'llitli glass or enp is eustomarily used h v many persons. and oftentimes without any rteansin r hetween the uses.

The invention will he hest understood from a eonsiderati n ot' the following detailed deseription. taken in eonneetion with the aeeompanrine drawings forming a part of this speritieation. with the t'urther understanding that while the invention is shown as applied to a partieular form of drinking enp. it is h no means limited t an. striet eont'orinit v with the showing of the drawingsdmt maybe variouslyehanged and modified in its praetieal emlmdiments. so long as sin-h emhodiments eontain no marked departure from the salient features oi the inrention.

Fig. 2 is a perspeetire view of the hlank i'olded intermediatetv and diselosin; the seeond step in the proeess of making the rap. Fig. 3 is a perspeetii'e view illustrating the third step in the produetion ol' the eup. Fig. 4 is a perspective view illustrating the fourth and final step in the production of the eup. Fig.

From the web 1 there savored a section 2 of suitable length to uli-inmluly make 9, cup, the section 2 being subsizmiinlly twice fie length of the finished cup and somewhat \"ilsr than the finisheol cup, the latter lasing usually produced in a list condition to be subsequemlyopenecl up for the weception of a liquid.

ters Patent for an apparatus for making ward. The folded blank is presented to marginal folding devices 10 shaped to produce the fold 4, and this fold having been formed the blank is presented to other rollers 11 spaced to engage the folded portion 4 of the blank, and that portioirof the body of the blank opposed to the folded portion 4, these rollers baring their peripheries milled, as indicated at 12, in like manner to the milled portions fly/of the rollers 8. The rollers 11 feed the ,folded blank with the marginal turned-over portions 4 to other shaping members 13 constructed to produce the additional fold 6 along the sides of the blank, and after this fold is produced the blank reaches other rollers 14 having marginal milled portions 15 engaging the folds 6 and that portion of the blank opposite the folds to mill or crimp the 'folds 6 and the opposed portions of the body of the cup, but to suitably discharge;the then completed cup into position to be accessible tothe operator. The several rollers S, 11

and 14 are so adjusted as to compress the material of the cup where engaged by the rollers to cause a coalescence or adhesion of the surfaces subjected to the pressure, whereby the paraffin of the paraffin paper is caused to coalesce to a sufiicient extent to seal the folded-over portions as though united by an adhesive, the adhesion being sufficiently firm for the purposes of the present invention.

When, a self contained and suitably protected mechanism is employed for the production of the cups the latter are nothandled at all in any stage of the manufacture and are delivered directly to the intended user, whereby the cups are truly sanitary and individual to the user and there is no possibilitv of contamination of any kind as is liable to occur in the so-called sanitary cups which of necessity are practically handled by numerous persons between the tiin' of manufacture'and the time of delivery of the cup to the user.

This application is a division of application Serial No. 688,488. filed by me on April 5 1912, for improvement in sanitary drinking cups.

\Vhat is claimed is:

1. The method of producing sanitary drinking: l'll]). which consists in first folding? a blank in the form of a sheet intermediatclr upon itself. and then beginning at the outer ((l 1f( of the intermediately folded blank folding each side toward the center line thereof e plurality of times to imprison the first fold in the second fold and thus close the sides of the cup against the escap of liquid placed therein.

2. The method of producing sanitary drinking cups which consists in folding a blank charged ,with material capable of cohesion under pressure at atmospheric tem- 'perature intermediately upon itself, and then beginning at the opposite outer side edges so of the folded blank folding the sides toward the center line of the blank and exerting suiiicient pressure upon the side folds to cause cohesion of the material of the blank at such folds at atmospheric pressure. 35

3. The method of producing sanitary drinking cups which consists in folding" an elongated rectangular blank of paper intermediate of its length, then beginmng'at the opposite outer edges of the folded blank folding said edges toward the center line thereof and again folding the folded side edges toward the center line of the folded blank in the. same direction as before to thereby imprison the first fold bet ween the :second side fold and the body of the cup.

4,The method of making sanitary drinking cups from elongated blanks charged with material capable of cohesion under sufficient pressure at. aln'iospheric [cmperature, which consists in first folding the blank intermediately of its length to brin' the two portions of the folded blank imp gether an'd compressing the marginal ,piu'- tions of the sides of the. folded blank til-{ gether. then folding over the side portions} toward the center line of the foldedildanlcf and compressinl said side folds. :llHllllKli folding orcr the folded side portions of the blank toward the cenler line and compress 1 10 log such doubly folded portions togcthemi the pressure being suflicicnt lo cause ((llHf l sion of tbe charging material of the coirtiguous surfaces at atmospheric tempera? i t-ures.
